Definitions

  • the invention is based on an orthodontic bracket with the features specified in the preamble of claim 1.
  • brackets have been known for many years.
  • a great advantage of such brackets is that they can be made very easily by welding a metal strip, which has at one end a bent portion for forming the bracket, to a base plate.
  • This stirrup can be pivoted between an open position in which a wire can be pushed between a free end of the stirrup and the base plate and a closed position in which the stirrup engages an inserted wire and encloses it between the base and the base Metal strip is bent.
  • brackets have been widely used by orthodontists for more than 25 years and are highly valued for their ease of handling. For patients Such brackets have the advantage to be very flat and therefore to offer a high wearing comfort, especially when used as a lingual bracket.
  • brackets are sometimes referred to as 2D brackets.
  • Brackets which allow transmission of torques in three directions, are known in the art in a variety of forms, for example US 2005/0019719 A1 . US 2002/0034715 A1 . US 4,669,980 and EP 1 332 726 A1 , However, such brackets are much more expensive to manufacture, for the orthodontist difficult to handle and offer a lower wearing comfort, since they can not be made so flat.
  • the object of the invention is therefore to show a way, as with a simply constructed bracket of the type mentioned on teeth in three directions a torque can be exercised without compromising the comfort or significantly complicating the handling of orthodontists.
  • a retaining tab By adding a retaining tab to a known bracket, it is possible to achieve ingeniously simple way that torques can be transmitted in three directions via the bracket. Namely, by using a tension wire having a quadrangular or approximately quadrangular cross-section, the orientation of the wire with respect to the base of the bracket can be predetermined by the retaining tab. With the retaining tab can prevent twisting or tilting of the tension wire, so that in an additional direction, a torque can be applied to the tooth. In addition to turning a tooth about its longitudinal axis and a lateral tilting in this way, the inclination angle of a tooth can be corrected, which is referred to as "torquen".
  • the incredibly simple solution of adding a retaining lug to a known bracket only marginally increases the production costs of a bracket.
  • the retaining tab may in fact be formed as a metal strip, which is fastened with a portion cohesively on the base, preferably by welding.
  • the wearing comfort is not impaired by a retaining tab according to the invention, since this does not change the dimensions of the bracket, in particular perpendicular to the base.
  • orthodontists can treat tooth misalignments that require torquing of teeth just as easily as tooth misalignments that only require shifting, longitudinal turning or tilting of teeth.
  • the usual for orthodontists movement of inserting a tension wire under an open bracket of a bracket can be used in a Brackt invention also for inserting the wire under the retaining tab. Additional steps are not required.
  • the retaining tab could fix a wire by clamping.
  • the retaining tab is made of a hard material and rigidly attached to the base.
  • a square wire whose thickness is slightly smaller, for example, 0.01 mm or 0.02 mm smaller than the distance between a holding portion of the retaining tab and the base, can then easily slide between the base and the holding portion of the retaining tab.
  • a twisting of the wire is prevented, since this would require a bending of the retaining tab, which would require very high forces because of the hardness of the retaining tab.
  • the retaining tab may for example be made of hardened stainless steel, in particular cold-strengthened stainless steel, in order to be able to withstand the forces occurring during orthodontic treatment.
  • the brackets of brackets according to the invention may be formed as curved sections of strips secured to a flat portion of the base.
  • the brackets can then be pivoted by bending the metal strip between an open position and a closed position.
  • the straps are made of a softer material and therefore more flexible than the retaining tab, for example made of soft annealed stainless steel.
  • bracket 1 has a base plate formed as a base 2, with which it is adhered as intended to a tooth, and two curved bracket 3a, which are each formed as a curved portion of a strip 3.
  • the brackets 3 a are between an in FIG. 3 shown open position, in which between the base plate 2 and a free end 3b of the bracket 3a place for inserting a wire 4, and a closure position in which the bracket 3a engages an inserted wire 4 and includes between itself and the base plate 2, pivotally.
  • the strip 3 which is fixed with a portion 3c, preferably by welding, on the base plate 2, is bent.
  • the strip 3 is preferably made of soft annealed stainless steel, so that the bending of the stirrups 3 a required for inserting a wire 4 is easily possible.
  • the illustrated bracket 1 therefore additionally has a retaining tab 5 in order to counteract a twisting or tilting of a wire 4 enclosed by the brackets 3 a.
  • the retaining tab 5 is a metal strip arranged between the two brackets 3 a, for example made of cold-strengthened stainless steel.
  • the retaining tab 5 has a mounting portion 5d, via which it is materially connected to the base plate 2, preferably by welding or soldering.
  • the retaining tab 5 has a free end 5a with an adjoining holding section 5b, between which and the base 2, as intended, a wire 4 held by the bracket 1, that is, a wire 4 encompassed by the brackets 3a.
  • the holding portion 5b extends parallel to the base plate 2, to counteract a twisting or tilting of a square wire 4, as shown in the figures.
  • the free end 5a of the retaining tab 5 is rounded or beveled, which facilitates the insertion of a wire 4.
  • the retaining tab 5 is kinked or bent.
  • the retaining tab 5 has two kinks 5e, which preferably run parallel. In this way, it is achieved that both the holding section 5b and the attachment section 5d extend parallel to the base plate.
  • the holding section 5b is adjoined by a section 5c extending obliquely to the base plate 2, which in turn merges into the fixing section 5d lying on the base plate 2, which is connected to the base plate 2 by material engagement.
